About

I'm a full stack developer with over 7 years of experience crafting software across Pharmaceuticals, Telecommunications, Financial Services, Automotive, Technology and Tourism. I deliver solutions for desktop, web and mobile platforms, working closely with engineering teams, product managers and client stakeholders to ship high-quality products.

My core focus is building robust services with Java Spring Boot, .NET and Node.js, paired with modern React frontends. I'm currently deepening my cloud expertise as I prepare for the AWS Certified Developer – Associate certification, applying these skills to design resilient, cloud-native architectures.

I also explore the frontier of Agentic AI development, building intelligent applications powered by Large Language Models with LangChain and LangGraph. Outside of feature work, I care about CI/CD automation, observability and writing well-tested code that scales.
